Spring onions are frequently used in Asian cooking, especially in quick stir-fries and soups. Sliced or shredded spring onions, using both the white and green parts, are also used as a flavouring ingredient and a garnish on hot dishes of rice or noodles, or sprinkled over steamed or braised fish and meat dishes.
Shredding
Cut off the dark green top. Cut the light part lengthwise in half, then into strips.
Angle-Slicing
Start at the dark green top and slice at an angle, using the line of your knuckles as a guide. Slice right down to the root end; discard the root.
